| 摘要 |
The invention relates to a device (1) for frictionally coupling two coaxial components (4, 5, 41, 42), especially two shafts (41, 42) or a shaft (4) and a hub (5). Said device comprises a first, inner coupling element (2) having a conical, peripheral surface (22) and a second, outer coupling element (3) having a conical, inner peripheral surface (32, 52). The two coupling elements (2, 3) are suitable to be reversibly slid one onto the other in the direction of a longitudinal axis (11), thereby being elastically deformed in the radial direction in such a manner that the conical peripheral surfaces (22, 32, 52) come to rest one on another, and the two coaxial components (4, 5, 41, 42) are frictionally interconnected via the coupling elements (2, 3) owing to the radial forces caused by the elastic deformation of the coupling elements (2, 3). The device also comprises a hydraulic tool (6) which is capable of exerting an axial force on the second coupling element (3) in the direction of the increasing circumference of the peripheral surface (22) of the first coupling element (2). Hydraulic means (34, 54, 66′, 68, 58, 38) can be used to produce an oil-filled gap between the two peripheral surfaces (22, 32), said gap allowing the two coupling elements (2, 3) to be displaced with little friction. The device finally comprises securing means (7) which can be used to adjust a maximum possible position of displacement of the second coupling element (3, 31, 5) in the direction of the increasing circumference of the peripheral surface (22) of the first coupling element (2) so as to avoid an unintentional, uncontrolled slipping of the outer coupling element (3) from the end position when the oil gap pressure is modified during assembly or disassembly.
